Intrade.com publishes the “Intrade Gazette” every two weeks. The “Intrade Gazette” is essentially a newsletter that comments on the prediction markets’ take on any number of topics. Anyway, I just received the 1/28/2010 “issue” via email today, which I reproduce below. The previous (1/14/2010) issue is available on the web at http://www.intrade.com/Market_Moves/20100114/newsletter.html.

Intrade.com maintains an actively traded market for futures contracts which pay 100 points (where 1 point = $.10) in the event that a specific contingent event occurs and 0 points otherwise. Thus, prices represent “risk neutral” event probabilities. I have previously blogged about how useful prediction markets can be in assessing political events such as election [...]

I have had some interest during the past few years in studying the accuracy of so-called “prediction markets” such as Intrade.com.

For what it’s worth, here’s what the intrade markets are predicting for 2009 (as of 7am ET on 12/29/2008):
GM to announce a merger with another major auto manufacturer: 35%
More than US$25 billion to be injected into the big 3 auto-makers: 60%
Caroline Kennedy to replace Hillary Clinton in the US Senate: 53%
Guantanamo [...]
At this point, it would appear (on the basis of prediction market trading this morning) that the answer will likely be no. CNN.com currently lists 56 Democratic Senators, 40 Republican Senators, and 4 undecided Senate seats in the states of Alaska, Georgia, Minnesota, and Oregon. Here are the last trades this morning on [...]
Now that the election is over, it is interesting to compare the actual outcome with my naive “prediction” method which allocated Electoral College votes based upon a cutoff price point of 55 for the 102 state-by-state Intrade contracts. On the eve of the election (see “Prediction Markets Update: November 3, 2008“), the state-by-state contracts [...]
The 2008.PRES.OBAMA Intrade contract now trades at 90.5, whereas the 2008.PRES.McCAIN Intrade contract is currently trading at 10 (compared with 83.3 and 17.3 respectively as as reported in my last update on October 30).
On this, the eve of the 2008 election, the state-by-state contracts imply that Mr. Obama holds a 353-174 “lead” over Mr. McCain [...]
The 2008.PRES.OBAMA Intrade contract now trades at 83.3, whereas the 2008.PRES.McCAIN Intrade contract is currently trading at 17.3 (compared with 87.2 and 13.3 respectively as as reported in my last update on October 28).
The state-by-state contracts continue to imply that Mr. Obama holds a 364-174 “lead” over Mr. McCain (based upon my cutoff price [...]
